Yes, it does look much like the description!  Were you on the Thetis in 1889?   :P

Thetis, 9 Sept 1889
Position: N70 22 00 , W172 48 00
Near Wrangel Island, Russia
From 9.20 until 10.30 observed Aurora Borealis.  Display very slight on account of fog, escalating at 10.10 when a brilliant display took place, lasting about 3 minutes,  It was in the shape of a broad band of scintillating light combing most of the colors of the rainbow and stretching in an arch from East (pc) to NW (pc) about 15o at its center.

What is apparently interesting is, lots of folk were studying the sun and its spots that week because Haley's Comet was in the sky on May 19th and there was lots of speculation on its effect on sunspots and earthquakes.  Just examples:
Los Angeles Herald, Volume 37, Number 230, 19 May 1910
http://cdnc.ucr.edu/cgi-bin/cdnc?a=d&d=LAH19100519.1.1&e=-------en--20--1--txt-txIN------

and Los Angeles herald [microform]., May 19, 1910, Image 1
